A screen S is supported by rib 25, ledge 26 and portion '7, and isspaced from the body and forms a partition of substantial area throughwhich sufficient oil may pass by gravity to the inlet 17, but cottonwaste and other impurities will be held away from the inlet. is used,the suction created by the pump piston 11, applied to a restrictedpassageway, tends to force lint and dirt through the screen to a greaterdegree than where a large screen as shown is utilized, resulting instopping up the inlet.

An upstanding lug 2'7 near the forward end of the body is arranged toengage the lower portion of the journal when the box is jacked up, toprevent injury to the bell crank fulcrum, and a lug 28 immediately belowlug 27 serves to transfer pressure from the lower wall of the box to thejournal in a straight line.

A perforated plate 29 is bifurcated at its ends as indicated at 30 toreceive the upstanding inner end of the body and the upstanding bellcrank 12-43 at the outer end of the body. This plate serves to support aquantity of cotton waste W in contact with the journal whereby thelubricant supplied through cup 19 may be distributed by capillaryattraction over the entire journal surface.

Plate 29 extends from side to side of the box and, preferably, lugs 31are brazed to the inner wall of the journal box as shown to engage theends of plate 29 and hold the same in position. An upstanding flange 32on plate 29 is provided with a toothed upper edge 33 to engage the wasteand prevent its working out past the end of the journal and interferingwith the operation of the bell crank. Plate 29 positions the lubricatorat the center of the box as illustrated.

Figure 5 illustrates how the lubricator and plate 29 may be insertedwhen the journal and the lower wall of the box are spaced apart byremoval of the brass and wedge.

The downwardly inclined passage 19 insures the feeding of oil into thelower portion of the end chamber even though a new thick bearing is applied to the journal thereby tending to telescope members 9 and '7 tothe maximum degree. This inclined passage is readily drilled through thetop of chamber 8 before the closure 80. is applied thereto.

In the modification illustrated in Figure 6, the elevated lubricantchamber is eliminated and the oil is discharged direct from the pumpcylinder 35 through a flap valve 36 into the lower portion of thedischarge chamber 3'7 from whence it rises through the sleeve 33 intothe discharge cup 39. The forward portion of the body and the remain ingfeatures of the lubricator are substantially as previously described.

Figures 7, 8 and 9 show a modified form of bell crank whereby the deviceis arranged for use in connection with a type of journal box having theshoulder 40 throughout its middle portion. This is the type used on somerailroads and this box would not accommodate the plain bell crank 12-13shown in Figure 1.

In this form of the invention the pump plunger is operated by a crankarm 41 secured to a ful- If a relatively small screen cruzn pin 42journaled in the cars 43 on the lubricator body and extending laterallybeyond one of these ears as indicated at 44 to mount the lower end 45 ofthe outer bell crank arm which extends outwardly beyond the end of thepin and then forwardly and upwardly as indicated at 46 and then inwardlyas indicated at 47 to engage the central portion of the journal. Byshaping the outer arm of the bell crank as described, the same, whendepressed, can pass around the side of the shoulder portion 40 of thebox as indicated at 48 thereby permitting insertion of the lubricatorand plate 49. A suitable lug 50 on the front end of the body of thelubricator is adapted to engage shoulder 40 on the box to hold thelubricator in position.

All forms of the invention are so constructed that they may be appliedto standard A. R. A. journal box without any changes in the latter andwithout removing the box from the journal when the lubricator is to beapplied or removed. The device is economical of manufacture and simplein operation. The mounting of the screen and the disposition of thesupporting lugs eliminate difficulties which have been encounteredheretofore in similar devices, and the various other novel featuresdescribed contribute to the effectiveness of the device for its intendedpurpose.

Obviously modifications other than those illustrated and described maybe made without departing from the spirit of the invention, and Icontemplate the exclusive use of any variations which come within thespirit of my claims.

I claim:

1. In a railway journal lubricator, a body portion adapted to rest onthe bottom of a journal box and including a pump cylinder, a pistontherein, a lubricant receiving chamber above the level of said cylinder,a vertically disposed discharge chamber adjacent the end of saidcylinder, a downwardly inclined passageway leading from said elevatedchamber to the lower portion of said discharge chamber, a dischargesleeve telescopingly mounted in said discharge chamber, and a dischargecup carried by said sleeve.

2. In a railway journal lubricator, a body having a hollow interiorforming a pump cylinder, there being an inlet port through the wall ofsaid I body to said cylinder, 2. downwardly projecting lug on said bodyfor supporting the latter above the bottom of a journal box, adownwardly extending rib on the bottom of said body, laterally extendingribs on opposite sides of said body, and a screen extending between saidribs and lug and along the lower portion and sides of said body and oversaid inlet port, said ribs. and lug reinforcing said body andmaintaining said screen spaced from the sides and bottom thereofwherebyoil may flow to said inlet port from three directions during operationof the pump and the screening area is substantially wider than saidbottom. a

3. In a railway journal lubricator, a pump, a discharge chamber at theend thereof, a discharge sleeve telescopingly assembled with saidchamber, a discharge cup carried on the upper end of said sleeve, 2.spring supporting said sleeve in said chamber, said sleeve and cuphaving a concave-convex engagement with each other whereby said cup mayassume various angular positions relative to said sleeve to facilitatecontact between said cup and the journal, to be lubricated, and a hollowrivet loosely holding said cup and said sleeve together.

4. In a railway journal lubricator, a body arin Y ranged to rest on thebottom of a journal box, said body having an upwardly disposed chamberat its inner end, a spring mounted journal-contacting elementtelescopingly supported above said chamber, and a supporting rib on thebottom of said body between said chamber and the outer end of said bodyfor engaging the bottom of the journal box the inner end of said bodybeing tiltable downwardly about said rib as a pivot when the box isjacked up far enough to force said element to the limit of itstelescoping movement relative to said chamber.

5. In combination, a railway journal, a journal box mounted thereon thecentral portion of the lower wall of said box being offset upwardly, alubricator body mounted on the center of the main portion of the bottomwall of said box, a pump piston rod projecting from said body, a pinextending transversely of said rod and journaled on said body, a crankdepending from said pin in front of said rod, and an operating leverextending forwardly and upwardly from the end of said pin at the side ofsaid offset portion of the box lower wall and then transverse- 1y toengage the end of said journal.

6. In a railway journal lubricator, a pump cylinder adapted to beapplied beneath the journal, an upwardly disposed discharge chamberadjacent said cylinder for conducting lubricant to the journal, and apassageway leading from said cylinder to the lower portion of saidchamber, said passageway being inclined downwardly towards said chamberto prevent the return of lubricant therethrough to said cylinder.

7. In a railway journal lubricator, a pump cylinder adapted to beapplied beneath the journal, a lubricant receiving chamber adjacent saidcylinder, a passageway connecting said cylinder and said chamber, acheck valve in said passageway, a lubricant discharge passage adjacentsaid chamber, and a conduit connecting said chamber and said dischargepassage and disposed downwardly towards said passage to prevent thereturn of lubricant therethrough to said receiving chamber where itwould impede the operation of said check valve.
